Adjusting the Lift
Adjusting the arm
• With the vest on, attach the arm
and undock the rig as before.
• Stand with the sled off your left hip,
with the lens slightly crossing your
body.
• Move the arm to the middle of its
boom range and let it rise or fall.
Do not completely let go of the
sled.
Setting the lift capacity of the arm
Now it’s time to adjust the arm for the weight of your camera.
Important: The lift
adjustment knobs can
only be turned when the
arm segments are slightly
above horizontal. They
cannot be turned when
the arm is unloaded, i.e.,
when not lifting the sled,
nor if the arm sections
are boomed too far up or
down. Do not force the lift
knobs. At the right angle,
they turn very easily.
• Ideally, each section of the arm
should come to rest slightly above
horizontal, about 5º to 10º.
• Adjust the arm section nearest the
sled rst (the forearm section).
• If the arm oats at too high an
angle, pull the sled down with your
left hand until the forearm section
is about 5º above horizontal.
Turn the weight adjustment knob
counterclockwise until the forearm
wants to oat at this angle.
• If the arm oats at too low an angle,
pull the sled up with your left hand
until the forearm section is about 5º
above horizontal.
• Repeat the process with the upper
arm section, but this time try to get
the upper arm to follow the forearm
as you boom up and down.
• Turn the weight adjustment knob
clockwise until the forearm wants to
oat slightly above horizontal.
• Keep making small adjustments
until the forearm settles at a 5º
angle up from horizontal.
• Remember, the weight adjustment
knob turns freely when the arm
section is slightly above horizontal.
Never force it or use a tool to adjust
the arm lift.
